This heavy-duty grinder pump is designed to deliver serious power as a new or replacement pump for residential and light commercial wastewater applications.

The Little Giant 16G Series, a heavy-duty 1 hp grinder pump, is designed to deliver serious power as a new or replacement pump for the most challenging residential and light commercial wastewater applications. This new pump is available in both 115V or 230V models.


The cutting mechanism produces over 745,000 cuts per minute. The forceful 1 hp class F motor provides optimal power to prevent flushables and other debris from clogging and causing downtime; the discharge is customizable to a contractor’s needs. Installers can choose to use the 1-¼ in. discharge or use the 2 in. adapter pre-assembled to the pump. This versatile option makes the 16G series the ideal drop-in replacement for any effluent or sewage pump struggling with clogs and binding, regardless of discharge size.


The 16G features a silicon carbide mechanical seal that provides up to six times longer seal life with lower thermal expansion and higher abrasion resistance when compared to carbon-ceramic seals. Furthermore, the 20 ft power cord is easily replaceable and is sealed at the connection point for unit protection against water. 


Both 115V and 230V options are offered with vertical and tethered float switch options.
